SPECIFICATION formingpart of Letters Patent No. 682,906, dated September 1'7, 1901. Application and any 17,1900. stanno. 23,936. mummia' To all whom it may concern;

Beit known that I, CHARLES EDWIN BLUE, a citizen of the United States, residingat Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Machines for the Manufacture of Glassware, of which the following is a specification.

My invention relates to improvements in machines for the manufacture ot' glassware,

K which will be fully described hereinafter.

This invention has in view, first, the combination -of speciallyconstructed blow and press molds whereby a plurality of blanks can be simultaneously pressed and the said` sectional plan View on the dotted line 2 2 of Fig. 1. Fig. 3 is a plan view of the revolving member, showing five molds thereon instead of two, as in Fig. 2. Fig. 4 is a plan View of the revolving member, showinga plurality of sets of separate blow and press molds. Fig. 5 is avertical central sectional viewof one of the press-molds used in Fig. 4..

Fig. 6 is a similar view ot'` one of the blowmolds used in Fig. 4.

The preferred form of'y my invention is shown in Figs. 1 and 2, and these will be first described. In said figures of the drawings, a

kis a mold-body having a plurality ot' blowcavities b, which are adapted to receive the insertible and removable press-molds cand the insertible and removable blow-mold bottoms d. A presser-head c is provided, which has plunger-openings f, which are so located that they are directly over the blow and press molds, respectively, when they are being used.

c The blow-head h is adapted to rest upon the neck-ring and is constructed to be simultaneously in communication with both the blowmolds. Any suitable mechanism can be provided for inserting and withdrawing the press-molds blow-mold bottoms and for operating the plungers.

As here shown, the

blow-mold bottoms are inserted and with-` drawn by hand, through the medium ot any suitable handle, as t',- and the means here shown for controlling'the press-molds is a cyl- Air or other fluid inder A and piston-.13. pressure is admitted to opposite ends of the cylinder through the pi pes C and is controlled by a suitable valve D, held normally upward by means of a spring E and `adapted'to be depressed by a footpiece F.- The upper end ot' tho piston-rod is adapted lo engage with a vertically movable press -mold support Gr.y

The presser-head in this machine is providedl with two plungers Lwhich are simultaneously carried into their operative position within the press-molds, and it is hi ghlydesirable that these plungers, though simultaneously operated, should be capable of an independent movement to accommodate 'themselves to any variation in the quantity of glass placed in the respective molds. This may be accomplishedin several ways, one instance being that, as here shown, the plungers al'e simultaneously though independently actuated, which will permit them to have independent movements, as just described. The instance here shown consists in providing a corresponding number ol'eylinders J,carrying pistons K, to which the u pper ends ofthe plunger-rods are connected. Air or other uid pressure is admitted simul- `taneously to opposite ends of these cylinders tions in the quantity of glass supplied to the` press-mold with which it is coacting, as Will be readily understood. The blow-head 7L may be raised and lowered in any convenient manner, or by hand, and the blow-head is provided with a pipe L, which will be in communication with anysuitable source ot pressuresupply.

In Fig. 3 I show a modification of the construction shown .in Figs. 1 and 2 in that in said ligure there are'shown live sets of molds instead of two, as shown in Figs. 1 and 2.

In Figs. 4., 5, and 6 I show the blow-molds so constructed that the press-molds do not IOO be blown.

move therein, but are isolated therefrom, the

"sets of 1molds l, 2, 3, and 4L of Fig. t each con-V taining two press-molds and two blow-molds. In this instance the presser-head e is lifted from the press molds and the suspended blank carried to the blow-molds or the blowmolds' carried to the suspended blanks and then the blank lowered into the said mold to In other respects the construction to be used in connection with Figs. 4, 5, vand 6 may be the same as that shown in connec- 'tion with the molds in Fig. l.

By means ot Vthe novel construction, combnation, and relative arrangement of the parts herein shown and described I am enabled to nearly double the output of machines of this character heretofore produced, and which is therefore a great step in cheap'ening the production of blown articles.

Having; thus described my il'ivention, what "tion with the blow-molds.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
